On macOS, NextPVR supports IPTV, HDHomeRun tuners, and SAT>IP tuner (DVB-S, DVB-C, DVB-T).
Running on a Mac, you have the option of either installing natively, or running via Docker.
Before installing NextPVR you need to have the .NET Core 3.1 runtime installed. This can be downloaded from https://dotnet.microsoft.com/download/dotnet-core/thank-you/sdk-3.1.201-macos-x64-installer
Download NextPVR from http://nextpvr.com/stable/mac/NPVR.zip. Copy binaries to directory an NPVR directory in your home directory, and execute the following commands from a terminal window.
cd NPVR
dotnet ./NextPVRServer.dll
After this, the NextPVR can be accessed via a web browser at http://localhost:8866/index.html
To watch video in the web app on a mac, you'll also need to have ffmpeg installed on the machine. You'll also find it easier to use Chrome than Safari if you intend to view video in the web application, since Safari actively tries to stop NextPVR from autoplaying any (on the assumption it's some advert trying to autoplay)
